Network Cabling

Which of the following are the standards for Twisted Pair cables?

• Two copper conductors form a path for an electrical signal with each wire carrying an equal but opposite signal.

• Wires are twisted to reduce crosstalk.

• Most cables contain 6 twisted pairs.

• cables may contain 25 to 100 pairs when used in larger wiring applications.

Which of the following are advantages of Twisted Pair cables?

• Flexibility

• Less expensive than other types of cabling

• Easy to work with and install.

• Newer, faster network protocols and standards have been designed to run on twisted pair cabling.

• Cables are pleasing to the eye and look more organized than other cables.

Twisted pair cabling is susceptible to interference and eavesdropping.

• True

• False

What does UTP stand for?

What does STP stand for?

UTP cables are not easy to work with and are more expensive than shielded cables.

• True

• False

The main purpose of shielding is to minimize the effects of EMI from external sources, such as fluorescent light ballasts.

• True

• False

Which of the following are true for STP cables?

• shielding is electrically conductive foil or braided materials wrapped around pairs of wires.

• shielding helps to minimize cross talk

• shielding can be used as a ground.

• STP are less expensive than UTP.

_________ is a part of a building that provides a pathway for the airflow needed by heating and air conditioning systems, such as above a dropped ceiling or below a raised floor.

• Riser Space

• Plenum Space

• STP

• UTP

Plenum rated cables use insulation that is fire resistant and non-toxic when burned.

• False

• True
